A plurality of through holes 23 distributed in an annular shape are correspondingly opened inside the outer edges of the docking joint 21 and the sealing gasket 22.

[0029] In this embodiment, the sealing gasket 22 is provided to improve the sealing performance of the connection between the butt joint 21 and the fixing sleeve 4 .

[0030] On the basis of the above structure, the through holes 23 and the limiting columns 5 are arranged in a one-to-one correspondence, and the docking joint 21 is movably sleeved on the outer side of the limiting column 5 through the through holes 23 .

[0031] In this embodiment, the initial docking between the docking head 21 and the fixing sleeve 4 is facilitated by the one-to-one corresponding through holes 23 and the limiting columns 5 .

[0032] On the basis of the above structure, the butt joint 21 and the fixing sleeve 4 are in contact and sealed, the interface between the butt joint 21 and the fixing sleeve 4 is arranged in an adaptive inclined shape, and the outer surface of the fixing sleeve 4 away from the butt joint 21 is provided with a threaded structure.

[0033] In this embodiment, the threaded structure provided on the outer surface of the fixing sleeve 4 is utilized to facilitate the installation and adjustment of the tightening sealing assembly 7 .

[0034] On the basis of the above structure, the support frame 6 includes a horizontal portion and vertical portions located at both ends of the horizontal portion. The vertical portions at both ends of the support frame 6 are welded and fixed to the outer wall of the fixing sleeve 4 .

[0035] In this embodiment, the support frame 6 is provided to facilitate the synchronous operation of multiple tie rods 73 in the tensioning sealing assembly 7, which is convenient for control and quicker to operate.

[0036] On the basis of the above structure, the tensioning seal assembly 7 includes an adjusting ring 71, a mounting ring 72, a pull rod 73 and a guide groove 74. The adjusting ring 71 is threadedly sleeved on the outside of the threaded section of the fixing sleeve 4. The left end bearing of the adjusting ring 71 is connected to the mounting ring 72. The left outer wall of the mounting ring 72 is connected to multiple pull rods 73 that are rotated at equal angles. A guide groove 74 is provided inside one end of the pull rod 73 close to the mounting ring 72. The other end of the pull rod 73 is hook-shaped, and a through groove is provided in the middle of the hook-shaped end of the pull rod 73.
